Schwarzschild black hole perturbed by a forcefree magnetic field
Abstract
We envisage a black hole perturbed by a forcefree magnetic field (FFMF) outside and attempt to determine its structure. We suppose the metric that describes this black hole is of the static spherical type, that is Schwarzschild, and the energymomentum tensor emanating from an FFMF source perturbs this background metric, in this regard one can imagine a magnetic accretion disk around the black hole. By solving the equations for such a configuration, we will show that in addition to modifying the diagonal elements of the background metric, we will also see the nonzeroing of the offdiagonal elements of the general metric, one of the immediate consequences of which will be a static to stationary transition.
